| Extension | .xcf |
| Category | images |
| Programs | CorelDRAW Graphics Suite X7 CinePaint Seashore KolourPint |
| Main program | GNU Image Manipulation Program (GIMP) |
| Description | The .xcf file format is an integral part of the GIMP software, which stands for GNU Image Manipulation Program. This format stores the complete composition of a GIMP image, including layers, channels, and paths, among other components. The .xcf format is designed to securely retain all information that a GIMP-processed image might contain. However, its specialized nature means it doesn't have widespread support outside of GIMP. For broader accessibility, images in the .xcf format are often exported to more universally recognized formats like PNG or JPEG. |
| Technical details | .xcf, as GIMP's proprietary file format, supports in-depth image editing. It includes a range of key features. Layer support allows for managing multiple image layers, crucial for complex edits. Channel and path storage enables the storage of alpha channels for transparency and vector-based paths. Editable text layers are also supported, ensuring text quality remains intact during modifications. To manage file size, it employs RLE compression to reduce file size without data loss. The undo history function enables the storage of undo history, allowing changes to be reversed even after the image is closed and reopened. Guide and grid features provide non-printing alignment aids. Color profiles ensure consistent color reproduction across various devices. This format also retains resolution data, vital for printing. It is extensible, meaning it's designed to accommodate future improvements while maintaining backward compatibility. In terms of compatibility, GIMP provides the most comprehensive support, while other editors offer limited support. Generally, the file size is larger than compressed formats like .jpg or .png due to the storage of additional information. Non-destructive editing ensures edits can be made without losing original image data. There is no quality loss, meaning the quality is preserved throughout editing sessions, unlike lossy formats. Adjustable layer effects and filters are stored within layer effects and filters. The .xcf format is particularly well-suited for temporary storage of editable images, especially complex ones. For final distribution, this format is often exported to formats like .jpg, .png, or .tiff. |
